Abstract

This paper presents a performance evaluation of TCM schemes over ISI channels with receivers using equalization. The asymptotic gain introduced by TCM coding schemes using the Ungerboeck´s (1982) criterion is derived in taking into consideration the effects of the channel impulse responses. Based on an approximation of the asymptotic gain, the effectiveness of a TCM coding scheme using the Ungerboeck´s criterion applied to a particular ISI channel can be assessed. Depending on the channel impulse response (CIR), a TCM scheme using the Ungerboeck´s criterion can have an inferior performance as compared to the uncoded system
